Dilbert became famous for holding a mirror to corporate culture, and ringing true. Now it is holding a mirror to how the right perceives culture to be. My complaint is that it is 1. Overly concentrating on issues that aren't issues for a large part of the population (I don't list my pronouns, but I don't care a single bit if someone else does, and I will respect their preferences in the same way I will respect that Margaret goes by Lisa since she doesn't like the name she was given).
2. Highlighting issues that just aren't real, i.e. diversity hiring (I have done plenty of hiring at multiple companies in multiple countries, we actively try to get expand the diversity of our APPLICANT pool. Evaluation and job offers are done on the merits. Never seen a diversity quota) What I haven't seen is people being passed over for not being diverse enough on a first hand basis. The people that claim it happened to them, are generally better at complaining than they are at their job.
To put it simply, people think Dilbert has gone off the rails, because they don't recognize the situations being represented as anything close to realistic.
